I've had 3 of them crack on my Cavy so far. The first because I didn't have the right tools. And one about every 5-6 oil changes after that. Never cross threaded one, but the last two have just had the flange pop off when I tried to re-install them. It's gonna happen, plastic gets a little brittle after so many heat cycles.

I've seen a couple that look like someone either tried to remove it with vise-grips, or else tried to chew it off. I'm not sure which.

I don't know if this is helpful or not but I found that in the Detroit area here Murray's discount auto carries AC Delco (OEM) filters for LSJ. They also have the special socket tool for removing the cap. Actually, I'm not sure if this was a freak occurrance or what but the first time I went there and bought the filter for like $10 and was kind of pissed it was so much more expensive than what I am used to. Then when I got home to change the filter I opened up the box and in with the filter was a cap and o-ring. So now I have two in case the original one breaks.

Hey RJ, you need to pick up a couple of those, so next time I'm in town I can buy one off you ... having an extra cap sounds like a really good idea.

Your Oil Filter Has Virtually Nothing To Do With Your Car Performance Wise. You Will Not Gain Or Lose Any Power Or Torque No Matter What Brand Of Filter You Use. It Is Not Like An Air Filter Where Some Have Better Filtration And Allow More Air Into The Motor Creating More Power. An Oil Filter Does Not Create Or Allow More Oil To Flow Through The Motor. Until K&n Comes Out With An Oil Filter, Fram Is The Best One Out There. Don't Worry About The Fact That The Aftermarket Filters Look A Little Different. Most Of Them Are Better Filters Than Oem.

I dont agree with that at all. I have seen aftermarket filters that are supposed to have and anti drain back valve on them and do not. That will do your motor abosultely no good at all.

I have used Mobil 1 filters in my other car for years. Complements the Mobil 1 oil I use nicely. I would disagree about the AC Delco filters being inferior to aftermarket. The AC Delco filters are some of the highest quality filters out there. That is all I will use on my 2.4l until Mobil 1 makes one for our cars. The AC Delco filters are as advertised (when they say they have a certain feature such as a drain back valve, they do), they have to conform to OEM specifications. I believe that there is test results out there that show the AC Delco, Mobil 1, and Wix filters are the best you can get. Surprisingly, the K&N oil filter didn't test too high (still above average). I am to lazy to find the link right now. The Purealator was rated very low IIRC. The Napa Gold, I believe, is a rebadged AC Delco or made by them.

If I had my choice, I would use AC Delco or Mobil 1...you can't go wrong with those two!

Just a FYI. My parts department carries 2 filters for the ecotec. One of them is a ac delco in a bag and the other one is a ac delco in the box. The one i the box is the one you want. If you take them both side by side the one in the bag from ac delco has a bigger hold inside. When it comes to filters of course you want to get the smaller so it can filter more. Ill see if i can get a shot of one up here of the 2 to show you the differnmce.

I was at my dealer 2 days ago and it was the same thing there one in a box and the other in the bag and they are different i was like WTF is this.

This is one of the very few good things about living in Germany and owning a cobalt! I can get filters on the economy out here (the filter itself is European design.. from Opel I believe) and they are abundant! Pretty cheap to! =P
